Deskpro M

Configuring System Board


The Deskpro 386/M and 486/M processor boards are upgradable to faster 486 and Pentium versions via the Processor Board Upgrade Kits. There are no microprocessor chip upgrades. The board upgrades come with the processor board, the latest version of EISA Configuration, and a system ROM. The upgrades are only available as a service part and pricing assumes return within 30 days of original processor board.
 
NOTE: There are no switch or jumper settings to set for the Pentium Boards
